This paper proposes a broadband Partially Reflective Surface antenna. It consists of a U-slot microstrip antenna as the source, an FR4 superstrate as the partially reflective surface, and a tapered corrugated ground structure. By employing the corrugated ground, the 3dB gain bandwidth is improved from 17% to 24% with the maximum realized gain and the 10dB impedance bandwidth unchanged. Therefore,...
A radiation pattern reconfigurable antenna designed using metasurface (MS) is proposed in this study. The pattern reconfigurable metasurfaced (PaRMS) antenna is composed of a planar semi-circular MS placed directly atop of a planar circular patch antenna with a diameter of 70 mm (1.2λ0), making it compact and low profile. The main-beam direction of the antenna has an angle of 32° from the boresight...
